Hi, I wanted to share this, whoever it may help.

I have Windows 7 x64 & Radeon HD card and also got the black terrain bug when I updated the drivers. However, this worked for me;

Modify this line in the Engine.ini -file located in "x:\Users\...\Anno1404\Config\Engine.ini":

<RE_TerrainRenderMode>0</RE_TerrainRenderMode> and change 0 to 1

Works with Catalyst 9.10 Beta.

mh.. the catalyst driver 9.10 BETA is older than the 9.9.

please try the catalyst 9.9 and post again.

Our members have no problems since patch 1.1.

I just install Win7 32bit today and I also had the black terrain and did the same thing that Reviisori did and everything is fine. Plus the copy of Win7 is not a RC or RTM. It a real copy from Microsoft. I just got my copies from Microsoft last week and I thought I would give them a try.

Plus my video driver is ati 9.9 the same one that I run in Vista with no problems. It must have something to with Win7, because the drivers are the same for both OS. I have not done the patch and I will not do it till see what happens with everybody else.

I can confirm that after the installation of patch 1.1 the black terrain bug is non-exsistent.

Win7 RTM 64bit, ATI 4870 with Cat9.9.

The bug is gone here also with patch 1.1 installed.

Vista 64-bit, ATI 4870X2, Catalyst v9.9.

I used Reviisori's option and that worked for me.
I have a ATI HD 4890 1gig videocard and catalyst 9.10.

Thanks Reviisori
